Razorsaw Deep-Cut Fine-Finish Dozuki 240mm

Blade: 240mm × 0.3mm, 25 TPI

Cut: Pull stroke, 60mm depth

Format: Deep-cut fine-finish dozuki (spined)

Replacement blade: RSS-371

Made in: Japan

A 240mm dozuki with 25 TPI and a deep-cut spine — the fine-finish saw for visible joinery work.

Japanese saws cut on the pull stroke. The blade stays in tension, which lets it be made wafer-thin without buckling. Less effort, narrower kerf, finer finish.

A dozuki carries a rigid back spine that keeps the blade straight through the cut. The trade-off is that the spine limits depth of cut to the body of the blade — but it makes the saw track dead-straight, ideal for tenons, dovetails, mitres, and any cut where a wandering kerf shows. The 371 is the deep-cut variant, with 60mm depth of cut. 25 TPI gives a glass-smooth finish on hardwoods; 0.3mm kerf is about as fine as a working saw gets.

Razorsaw — Japan’s craft-saw standard

Razorsaw blades are impulse-hardened — the cutting edges hold sharpness well past what a conventional saw can match. The teeth cannot be resharpened; the blade gets replaced. The matching blade for this saw is RSS-371.

Pairs with: the matching replacement blade — swap it when the teeth dull and the handle keeps going. See the rest of our Japanese saws.
